@Component
public @interface AutocollectedGenericDao

Indicates that a GenericDao implementation should be added as singleton bean to spring (and in a second step (by the @link DefaultDaoRegistry) to the DAO Registry). You can indicate as parameter the desired id for the spring bean. Requires config that looks something like the following (see sample for more details):

  1) collect GenericDao implementations with this annotation 

     <!--  This section scans for DAOs annotated with @AutocollectedGenericDao that should be
     added to the spring application context (as beans). Later, the DAO Registry
     automatically collects these DAOs. -->
     <!--    The attribute base-packages indicates the packages where we look for DAOs  -->
     <context:component-scan use-default-filters="false"
     annotation-config="false"
     base-package="ch.elca.el4j.apps.keyword.dao, ch.elca.el4j.apps.refdb.dao">
     <context:include-filter type="annotation"
     expression="ch.elca.el4j.services.persistence.generic.dao.AutocollectedGenericDao" />
     </context:component-scan>

  2) set up dao registry 

     <!-- Allows to register DAOs. Automatically collects all GenericDaos from the application context -->
     <bean id="daoRegistry"
     class="ch.elca.el4j.services.persistence.generic.dao.impl.DefaultDaoRegistry"/>


  3) init the session factory on the DAOs 

     <!-- Inits the session factory in all the GenericDaos registered in the spring application context-->
     <bean id="injectionPostProcessor"
     class="ch.elca.el4j.services.persistence.hibernate.dao.HibernateSessionFactoryInjectorBeanPostProcessor" />
